As I wrote about last week within the Supermicro H13SSL-N EPYC Turin motherboard review, one of the factors leading me to purchasing that EPYC 9005 series motherboard was that this board offered support for full 12 channel DDR5-6000 memory performance compared to some of the other lower-cost Socket SP5 motherboards offering just 8 memory channels. For those wanting to quantify the performance difference between eight and twelve memory channels with AMD EPYC 9005 "Turin" processors, here are some benchmarks for showing the workloads that can really benefit from all 12 memory channels and other workloads where eight memory channels can be largely sufficient if looking to minimize costs.
